What do delocalised valence electrons moving between nuclei do?
Delocalized valence electrons moving between nuclei become detached from their parent atom. The metal is held together by the strong forces of attraction between the delocalized electrons and positive nuclei.
What kind of bond does gold have?
Gold has metallic bonds.The electrons of the gold atoms are delocalised to form a sea of electrons. The gold atoms are held together by electrostatic forces of attraction between the negatively charged sea of electrons and the positively charged ions (the nucleus + the electrons that are not delocalised). Gold has high melting and boiling points because a lot of energy is required to overcome this strong electrostatic forces of attraction.
What type of bond holds the atoms together in chemical properties of iron?
The ions are held in the lattice by the electrostatic force of attraction between these positive ions and the delocalised electrons. This attraction extends throughout the lattice and is called metallic bonding.
What is the Coulombic attraction?
Coulombic attraction is the force of attraction between oppositely charged particles, such as electrons and protons. It is governed by Coulomb's law, which describes how the force between the charges depends on their magnitudes and the distance between them.
An increased distance of the electrons from the nucleus causes th be affected?
When electrons are farther from the nucleus, the electrostatic force of attraction between the protons in the nucleus and the electrons decreases, leading to weaker binding of electrons to the nucleus. This can result in higher energy levels for the electrons, potentially affecting the reactivity and chemical properties of an atom.
What do delocalised valence electrons moving between nuclei do?
Delocalized valence electrons moving between nuclei become detached from their parent atom. The metal is held together by the strong forces of attraction between the delocalized electrons and positive nuclei.
Which properties of the elements are related to the attraction between the nucleus and electrons in atoms?
These are the chemical properties.

What is the method of bond formation for metallic bonding?
metallic bonding occures due to the attraction force between the metal ions and the electrons.The outer most shell of a metal atom is free to move and therefore releases it into a SEA of electrons,once having released the electrons the metals become ionised(+) and are attracted to the electrons as they are -charged .This builds up to form a Giant lattice of delocalised electrons.

What is the method of formation for metallic bonds?
In metallic bonding, positively charged metal ions are surrounded by a "sea" of delocalized electrons. The electrostatic attraction between the positive metal ions and the negative delocalized electrons holds the metal atoms together in a lattice structure. This results in properties such as high electrical and thermal conductivity, malleability, and ductility in metals.
How do you identify the various types of bonds?
There are three types of chemical bonds. Ionic, covalent and metallic. Ionic is where a metal and a non metal combine and transfer electrons Covalent is where two non-metals combine and share their outer shell electrons Metallic is where you have a metal such as iron or aluminium. Inside the medal cation is a sea of delocalised electrons which create an electrostatic attraction between the positively charged cations (metal e.g iron) and the negatively charged delocalised (free moving) electrons. This is what makes some metals malleable because the bond is non-directional, meaning the cation can slide over each cation due to the constant attraction between the delocalised electrons.
What is the relationship between the atomic radius of chromium and its chemical properties?
The atomic radius of chromium affects its chemical properties. As the atomic radius decreases, the attraction between the nucleus and electrons increases, leading to changes in reactivity and bonding behavior.
What does a Aluminium bond look like?
metallic bond is the electrostatic force between the positively charged metallic ions and the 'sea' of electrons. Aluminium has 3 valence electrons, each of the aluminium atom will release the 3 valence electrons and form Al3+ (positively charged ion) and the valence electrons are no longer associated with a particular metal atom, instead they are free to move throughout the solid piece of metal, so called 'delocalised' electrons. The attractive force between Al3+ ions and the delocalised electrons is the metallic bonding in aluminium.
What is the strength of attraction between a nucleus and the outermost electrons?
The strength of attraction between a nucleus and the outermost electrons is determined by the electric charge of the nucleus (protons) and the distance between the nucleus and the electrons. This attraction is the basis for the force that holds atoms together and is essential for the stability of matter.
What happens during metallic bonding?
Metallic bonding is the electrostatic attraction between postive metal ions and the delocalised electrons surrounding them. Theese forces are very strong which is why metals have very high melting points. The more charge a ion has will increase its melting point as the electrostatic attraction will be higher.
